Overview
The ADM7160AUJZ-1.8-R2 is a fixed-output ultralow noise linear regulator manufactured by Analog Devices Inc., providing a stable 1.8 V output with a maximum load current of 200 mA. It operates within an input voltage range of 2.2 V to 5.5 V and features a typical dropout voltage of 150 mV at full load. The device incorporates a low quiescent current of 265 µA and achieves high power supply rejection ratio (PSRR) performance, reaching 54 dB at 100 kHz. Packaged in a compact 5-lead TSOT format, it includes integrated current-limit and thermal overload protection circuits.
Feature Summary
- Ultralow noise performance independent of the output voltage setting
- High power supply rejection ratio (PSRR) for effective ripple suppression
- Low dropout voltage enabling efficient operation across wide input ranges
- Integrated current-limit and thermal overload protection mechanisms
Applications
- ADC/DAC power supplies
- RF, VCO, and PLL power supplies
- Post dc-to-dc regulation
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and reel specifications. Confirm that the component meets all required environmental compliance standards for your target market. Ensure compatibility with standard surface-mount assembly processes for the designated package style.
Selection Notes
Select this regulator for applications requiring minimal output noise without external bypass capacitors. Verify that the input voltage remains within the specified operating range under all conditions. Consider the thermal resistance characteristics of the PCB layout when designing for high ambient temperatures or maximum load currents.
Part Context
This component belongs to the ADM7160 series of ultralow noise linear regulators designed for space-constrained analog front-end and RF applications. The series offers multiple fixed output voltage options ranging from 1.1 V to 3.3 V. It utilizes an innovative circuit topology to achieve superior noise performance while maintaining stability with small ceramic capacitors.

FAQ
Does the ADM7160 require an external bypass capacitor for noise reduction?
No, the ADM7160 achieves ultralow noise performance without the need for an external bypass capacitor.
What is the function of the EN pin on the ADM7160?
The EN pin enables or disables the output voltage. Driving it high turns on the regulator, while driving it low turns it off. An internal pull-down resistor holds the input low when left open.
